The article points out the drawback of all the current instructions for the lightning protection device: the lack of instructions for calculating the lightning protection zones of an object located on a slope. The methods of applying the current instructions for the lightning protection device when placing an object on a slope are given, based on the assumption that lightning strikes the lightning rods vertically and perpendicular to the slope. The features of the choice of lightning protection characteristics (calculated points of the protected object, calculated heights of lightning rods, methods of constructing lightning protection zones) are described. A method for calculating the lightning protection zones of an object located on a slope is proposed, based on the assumption that lightning strikes lightning rods perpendicular to the slope, in particular, the concept of the axis of a conditional lightning rod shifted on the object plan for calculating lightning protection zones is introduced. The consequences of the application in engineering practice of the methodology for calculating the lightning protection zones of an object located on a slope, based on the assumption that lightning strikes the lightning rods perpendicular to the slope, are indicated. Using a pulse voltage generator, tests were performed on a model of a lightning rod located on a slope in order to determine the direction of lightning strikes-vertical or perpendicular to the slope. It was determined experimentally that the proposed method for calculating the lightning protection zones of an object located on a slope, based on the assumption that lightning strikes lightning rods perpendicular to the slope, should be used in cases where the protected objects are located on slopes with an angle of more than 25°.

Noise-protected high charge voltage meter was manufactured using terminal capacitors of the four-channel pulse voltage generator (PVG). The noise protection is provided by the use of communication lines with fiberoptic cables. This measuring device is successfully used for the relativistic electron beam (REB) accelerator “Temp-B” and it provides the measurement accuracy of ~ 0.5% in the electromagnetic noise environment.

Abstract The paper is devoted to the development process of the geophysical pulse voltage generator. The peculiarity of the generator lies in the non-specific purpose of this type of construction. Its main function is the controlled effect on the active faults of seismically dangerous zones. The results of the field experiment with the constructed device from 2018 to 2020 are presented. During the experiments, estimations and theoretical analysis we have obtained the seismic noise recorded by means of molecular electronic instruments and determined the periods of the electrical pulses. Operational parameters of the generator were identified on the basis of experiment results. The software and hardware elements of the system were upgraded and, as a result, a new version of the geophysical pulse voltage generator was developed.

Surge Protection

The earth-termination system for towers of ground-based wind turbines in addition to protective and functional grounding provides lightning protection grounding, which is especially important since the wind turbine is susceptible to lightning strikes. If insufficient protective measures are taken, the risk of damage to a wind turbine due to a lightning strike increases. Therefore, a well-thought-out built-in grounding system for wind turbine towers is needed, which would function as necessary and guarantee long-term mechanical strength and corrosion resistance. The configuration of grounding systems for wind turbines is discussed in IEC 61400-24, which deals with the topic of lightning protection for wind turbines, including detailed information on the choice of lightning protection measures and surge protection. It is advisable to create a lightning protection concept at the initial stage of planning a wind turbine in order to avoid later costly repairs and retrofitting.
